Longitudinal data from a rural Ugandan cohort was used to estimate rates of unfulfilled need for contraception, defined as having unmet need and intent to use contraception at baseline but having an unintended pregnancy or with persistent unmet need for contraception at follow up.
Between 2002 and 2009 (5 survey rounds), a total of 2610 sexually active non-pregnant women with unmet need for contraception at the start of an inter-survey period were asked whether they intended to use any method of contraception until they desired a child. Modified Poisson multivariate regression was used to estimate unadjusted and adjusted prevalence ratios (PR) and 95% CI of unfulfilled need for contraception.
The proportion of women with unmet need at the start of an interval who intended to use contraception significantly increased from 61 to 69.1% (p < 0.05). However the majority of women who said they intended to use contraception had unfulfilled need for contraception at the subsequent survey (64.8 to 56.8%). In the adjusted analysis, significant predictors of unfulfilled need for contraception included age 40-49 years (PR = 1.34; 95% CI 1.04-1.74) and those with unknown HIV status (PR = 1.16; 95% CI 1.06-1.26).
There is a significant discrepancy between women's intent to use contraception (> 60%) and subsequent initiation of use (< 30%) with many having unintended pregnancies which might explain the persistent high fertility in Uganda. Future research needs to address unfulfilled need for contraception among women at risk of unintended pregnancies.
来自乌干达农村队列的纵向数据用于估计避孕需求未满足率,其定义为在基线时有未满足的需求且有使用避孕措施的意愿,但在随访时发生意外妊娠或持续存在避孕需求未满足的情况。
在2002年至2009年期间(5轮调查),共有2610名在调查间期开始时存在避孕需求未满足的性活跃非妊娠妇女被问及是否打算在想要孩子之前使用任何避孕方法。采用修正泊松多变量回归来估计未调整和调整后的避孕需求未满足患病率比(PR)及95%置信区间。
在一个间期开始时有未满足需求且打算使用避孕措施的妇女比例从61%显著增加至69.1%(p < 0.05)。然而,大多数表示打算使用避孕措施的妇女在随后的调查中仍存在避孕需求未满足的情况(从64.8%降至56.8%)。在调整分析中,避孕需求未满足的显著预测因素包括40 - 49岁的年龄(PR = 1.34;95%置信区间1.04 - 1.74)以及HIV状态未知的妇女(PR = 1.16;95%置信区间1.06 - 1.26)。
妇女使用避孕措施的意愿(> 60%)与随后实际开始使用(< 30%)之间存在显著差异,许多妇女发生了意外妊娠,这可能解释了乌干达持续的高生育率。未来的研究需要解决有意外妊娠风险的妇女中避孕需求未满足的问题。
